The ruler of Qatar, Emir Tamim bin Hamad Al Thani, hosted a gaggle of religious leaders at his palace in Doha to break the Ramadan fast on Tuesday of last week.

The emir physically embraced and accorded seats of honor to some of the most hateful clerics in the Gulf, religious leaders who together have a long record of intolerance toward women, Christians, Shiites, and Jews.

Footage from the event showed Tamim kissing the head of iconic Muslim Brotherhood ideologue Yusuf al-Qaradawi, who was seated even closer to the ruler than his ministers or brother, the deputy emir.

Qaradawi notoriously asked God in a 2009 sermon broadcast on Qatar's Al Jazeera network to "take the Jews, the treacherous aggressors" and to "count their numbers, and kill them, down to the very last one."

He has also chaired a network of charities called the Union of Good that is under US terror finance sanctions on charges of being a front for Hamas. Qaradawi then bragged that he himself had avoided being sanctioned because Tamim's father, the previous emir, stood up on his behalf.

Qaradawi has ceased giving televised sermons in the country. This was reportedly one of Qatar's concessions last year to end a diplomatic breach with its Gulf neighbors, a standoff exacerbated by the cleric's condemnation of those countries' anti-Brotherhood policies. Yet Qaradawi's peck from the prince suggests that the hardline preacher still continues to have access to Qatar's ruling circle.

Qatar's ruler also embraced a trio of Saudi preachers who were profiled in a March report on Saudi incitement and human rights abuses that I helped write for the nonprofit group Human Rights First. Mohammed al-Arifi, Aidh al-Qarni, and Nasser al-Omar have a combined 23 million followers on Twitter, in part because of the tolerance or support they receive from Gulf rulers.

Al-Arifi was recorded last Tuesday exchanging kisses with Tamim and speaking into his ear. Also last week, Qatar's Ministry of Islamic Affairs and Endowments announced it was "delighted to invite" guests to several events featuring Arifi at Qatar's massive state-controlled Grand Mosque.

Yet Mohammed al-Arifi has been accused of describing Shiites as "non-believers who must be killed," and of decrying them for "treachery" and "evil."

The Middle East Media Research Institute says he has also proclaimed "one's devotion to jihad for the sake of Allah and one's will to shed blood, smash skulls, and chop off body parts … constitute an honor for the believer." On Al Jazeera he called Osama bin Laden a "sheikh" and insisted members of Al Qaeda "do not tolerate bloodshed." According to Saudi women's rights activist Eman al-Nafjan, Arifi has also delivered guidance on how to beat one's wife.

Another Saudi preacher who exchanged kisses with Tamim that same evening was Aidh Abdullah al-Qarni, who was visiting the country to deliver several lectures for Ramadan. Qarni has previously stated that when Jews and Christians claim God loves them, "they are lying, Allah's wrath upon them." He also has hailed fighters of the US-designated Foreign Terrorist Organization Hamas as holy warriors, and maligned Jews as "the brothers of apes and pigs."

Finally, Saudi preacher Nasser al-Omar was also photographed holding hands with a grinning Tamim and sitting next to Qatar's Minister for Islamic Affairs and Endowments.

According to CNN Arabic, al-Omar once sought a meeting with the Saudi king to warn against "the danger" of granting women the right to drive, which the preacher warned would "open the door of evil." He also allegedly signed a petition in 2008 that called the "Shi[ite] sect an evil among the sects of the Islamic nation, and the greatest enemy and deceivers of the Sunni people."

On his website, al-Omar endorsed the Islamic Front in Syria in 2013, even though one of the group's leaders had already advocated ethnic cleansing of Shiites and Alawites, and its members had possibly participated in the summary execution of Alawite villagers.

On the most recent anniversary of the 9/11 attacks, Qatar agreed to participate in a coalition against the Islamic State, specifically pledging to repudiate the group's hateful ideology.

Perhaps it is time for Washington to remind Qatar of its commitment.
